Realme has introduced a new smartphone with an amazing 15,000mAh battery during their 828 Fan Festival in China on August 27, 2025. This phone can play 25 movies back-to-back or let you game for 30 hours on a single charge. It’s designed to be a portable power source, able to charge other devices like phones or wearables with a cable.
The phone is slim at just 8.89mm thick and uses a special battery made with pure silicon, which helps it stay light and powerful. Realme says it can last up to six days with normal use or even three months on standby in flight mode.
It might also have a 6.7-inch screen, a MediaTek Dimensity 7300 processor, 12GB of memory (with more that can be added), and 256GB of storage. The phone runs on Android 15 with Realme UI 6.0 and has a dual-camera setup on the back.
